Description

250Watts DC-DC converter module uses 2nd Generation power processing, control and packaging technologies to provide the performance, flexibility and cost effectivenes expected of a mature power component. For example, a plated-cavity core transforme couples widely separated primary and secondary windings, resulting in low in-to out parasitic capacitance and noise. High frequency ZCS/ZVS switching, advanced power semiconductor packaging and thermal management of 250Watts provide high power density with low temperature gradients. Extensive use of silicon integration results in 1/3 the part count of a 1st Generation converter.
